Queensland's worst hospital wait times revealed

UP TO 60 per cent of patients with imminently life-threatening conditions are waiting longer than recommended at Queensland's worst emergency departments, new data shows.

Logan, Ipswich, Gold Coast University and Redland hospitals were the worst performing in the state, with more than half the patients in the second or third most serious categories waiting longer than recommended times.

At Logan Hospital, a whopping 71 per cent of patients with imminently life-threatening conditions waited longer than the recommended 10 minutes.

Almost two thirds of patients with a slightly less serious potentially life-threatening condition also waited too long at Logan.

Caboolture Hospital also performed poorly, with 49 per cent of people with a potentially life-threatening condition waiting longer than the recommended 30 minutes to be seen by a doctor.

The figures show almost a third of patients across Queensland waited longer than recommended last month - a marginal improvement on November.

Across the state, waiting times were too long for 29 per cent of all patients who face imminent threats to their lives and 39 per cent with potential threats.

Hospitals performed much better for the most serious category of patients, whose conditions are immediately life-threatening, with 99 per cent seen within the recommended 2 minutes.

Logan, Gold Coast University, Toowoomba and Sunshine University hospitals all recorded blowouts in their waiting times between November and December.

Ambulance ramping - where patients are kept waiting on stretchers longer than 30 minutes - is occurring for up to 35 per cent of patients, the figures show.

Acting Health Minister Shannon Fentiman said emergency departments across the state had seen an increase in patients over the past financial year, with an extra 9 per cent of presentations in the most serious categories.

"Despite these demand challenges, a record number of people are receiving treatment within clinically recommended time frames in Queensland," Ms Fentiman said.

She defended the poorer results for those with imminent or potentially life-threatening conditions, saying these "patients have more complex conditions and it often takes more time to treat them".

But Opposition Leader Deb Frecklington said the results were an indictment on the state's hospitals.

"Queenslanders deserve a world-class health system and Labor isn't delivering," she said.
